An over-road test was performed for the purpose of determining the effect of various levels of spring stiffness and friction damping upon the ride quality of three different types of railroal cars. The primary difference among the three cars their bending stiffness. They were a 50-ft, 70-ton box car, a standard level piggyback flat car, and a wide body, fully enclosed, tri-level autorack car. Instrumentation consisted of spring deflection transducers, vertical and lateral accelerometers and strain gages. Data will be presented primarily in the format of plots of acceleration versus speed with supporting plots og spring displacement and roll angles.
